The launched KWin instance connects to your Wayland server, binds to the Shell and will create a ShellSurface. That you will get through a signal on m_shell - compare wayland_server.cpp:148. I would as a next step try to hook into this and see whether the surface gets created. Once you have that you can look into rendering it.

There's a damaged signal which you should use to trigger a repaint of your QQuickItem. When rendering you can access the buffer on the SurfaceInterface. If KWin uses KWIN_COMPOSE=Q you can access the buffer as a QImage and just render it. Pretty straight forward - hopefully. But first try to see whether you get the ShellSurface created. If not we need to look into what goes wrong.

  I am not getting how to proceed further now, can you please help me on this? Also, current confusion i have is, should kwin_wayland nested window appear when i run qmlscene? Because currently it does appear.
